The Polar men's FT7 heart rate monitor features tools that are designed for people who want to keep track of and improve their fitness. With a touch of a few buttons you can know if the main effect of your training is fitness improvement or fat burning. You can also track the amount of calories burned. Another great feature is the HR-based target zones function with visual and audible alarm. This function allows you to define your target zones for a training session based on heart rate to help define the right intensity. Each Polar FT7 heart rate monitor comes complete with the comfortable Polar WearLink+ transmitter and quick start guide.
